Co-founder of PayPal: Facebook could be "the most important companies in the world"

Max Rafael Levchin, co-founder and former CTO of PayPal, has had some good things to say on Facebook, today, the Goldman Sachs Technology and Internet Conference in San Francisco. Levchin and Bill Gurley of Benchmark Capital has responded to questions about "game-changing technology," one of which was the unprecedented growth of Facebook and its impact. Levchin reportedly claimed that Facebook could become the "most valuable companies in the world" if it can successfully replace core messaging "," according to Mashable:

"Facebook has monopolized all but white pages correctly," Levchin said, explaining that, when you want to find and connect with someone, go to Facebook. Unlike white pages, however, Facebook has also information on a person's interests, tastes and social graph. That alone has turned Facebook into a company of 50 billion dollars. However, Levchin says that becoming the repository for personal information that could lead to "" Facebook successfully replacing the core messaging. If it becomes the primary communication platform on the web, could become the most valuable company in the world.

As a side note, the giant social networking certainly wants to pull it off. Rumors say executives want to see Facebook to turn the company around the world the first trillion dollars.

Levchin founded another company in 2004: Slide, a personal media sharing to social networking sites like MySpace and Facebook. Google bought the company in August 2010 for 182 million dollars, and so now works for the search giant, as one of the many people of the company with the title "vice president of Engineering."

It is therefore no wonder that Levchin was quick to point out that Facebook should not be confused with demand generation, or request Discovery (search thinks). The Ukrainian-BORN computer scientist and entrepreneur says that he had read that signals social graph are not particularly effective in optimizing search related advertising. I would say that this may be for today, but what's coming tomorrow has simply not yet materialized. Facebook has some of the best engineering talent in the world.
